Built for runners 40+

Your training data is being read with the wrong thresholds.

Masters Running Analytics connects your training data to conservative, research-informed thresholds that adapt to your age bracket — surfacing risk signals earlier so you can stay consistent, season after season.

Not a medical device. Insights support training decisions and risk awareness — not diagnosis or injury prevention guarantees.

No generic averages. No new hardware. Connect what you already use.

Why Masters

Thresholds that reflect your decade

Thresholds that reflect your decade

At 55, a safe workload ratio isn't the same as at 30. Masters applies age-bracketed limits to ACWR and weekly progression — informed by published sports science.

Converging signals, not isolated numbers

Workload trends, HRV deviation, sleep quality impact, and biomechanical asymmetry are evaluated together. A single metric rarely tells the full story.

Twelve months of context

Rolling data retention lets you see how your body responds across training blocks, seasons, and life stress — not just this week's numbers.

The problem

Your body at 50 isn't your body at 30.

Most platforms use one-size-fits-all thresholds designed around generic populations. Masters Running Analytics uses conservative, age-bracketed thresholds informed by published sports science to surface risk signals earlier — so you can protect consistency, manage recovery, and keep training season after season.

How it works

Three steps to smarter thresholds

Step 01

Connect your running platform

Link what you already use — Strava, Garmin, or other supported sources. No new devices required.

Step 02

Age-adjusted thresholds applied automatically

Your age bracket sets the governing limits — ACWR danger zones, weekly volume caps, and recovery baselines adapt without manual configuration.

Step 03

Risk signals surfaced when they matter

When load, recovery, and biomechanical trends converge toward elevated risk, you get a clear alert with contributing factors and practical adjustment guidance.

Features

What the platform helps you do today

Currently available guidance, tracking, and review features. No inflated claims, no placeholder magic.

Training Load & Risk Signals

Age-bracketed ACWR thresholds and weekly progression caps informed by published research. When workload trends combine with HRV deviation, sleep-related risk factors, or biomechanical asymmetry, you see which signals are contributing.

ACWR trend | weekly progression | HRV deviation | sleep impact | asymmetry

Recovery Context

Alerts when HRV trends deviate beyond meaningful ranges and when sleep quality elevates risk context. The goal is to interpret recovery in a way that supports durable training decisions, especially during high-load phases.

trend deviations | context notes | risk modifiers

Training Plan Tracking

Import structured plans via iCal feeds or CSV upload. Completed workouts are automatically matched to planned sessions, showing adherence trends and load implications of missed or adjusted sessions.

match rate | adherence trend | missed-session impact

Shoe Management

Track mileage and rotation patterns across your shoe collection, with comfort degradation monitoring over time. Injury-aware suitability scoring helps inform shoe selection for specific training sessions.

Data Integrations

Connect your running platforms and let Masters unify your training timeline. Starting with Strava and Garmin, with more integrations planned. Rolling 12-month retention for evaluating patterns across training cycles.

Transparent by design

Age-adjusted thresholds

Conservative, research-informed values derived from published sports science — not a single validated model, but a synthesis of multiple evidence streams.

Sample outputs

What you actually see

Risk Trending Up

Moderate — elevated risk potential if trend continues

  • Primary signal: ACWR rising above bracket threshold
  • Contributing factors: HRV -12% over 4 days; asymmetry 6%
  • Worth considering: reduce intensity exposure; cap weekly increase to bracket limit; prioritise a recovery day
Return-to-Training Stability

Low risk, stable trends

  • Primary signal: progression within bracket cap; HRV stable
  • Worth considering: maintain plan; monitor asymmetry if >5% persists

Privacy-first analytics

Your data. Your control. No exceptions.

Your training, recovery, and biomechanical data is personal. We treat it that way.

No selling, no sharing. Your data is never sold, shared with third parties, or used for advertising.

Health data protection. Training and recovery data classified as health-related with GDPR special-category protections.

You control your data. Export everything or delete your account and all associated data at any time.

Data minimisation. Uploaded files are parsed and discarded — only the extracted records are kept.

Rolling 12-month retention. Strava API compliant. No dark patterns.

Who it's for

Built for experienced runners

Masters runners (40+) committed to the sport and tired of generic thresholds

Strava and Garmin users who want smarter interpretation of data they already collect

Runners returning from or managing recurring issues who need conservative load guidance

Distance runners who prioritise running longevity and consistency over chasing a single result

If you're experienced enough to know your body has changed, your analytics should reflect that — automatically.

Research foundation

Every threshold is informed by published research

We synthesise multiple evidence streams rather than relying on a single model — and we're transparent about what the research does and doesn't yet confirm.

FAQ

Common questions

No. Masters is designed to surface risk signals earlier and support better training decisions — not to promise injury-free running. Always consult a medical professional for pain or suspected injury.

Training tolerance and recovery capacity tend to shift across decades. Masters reflects that by adapting danger zones and progression limits to your age bracket, informed by published sports science.

Currently Strava and Garmin. Training plans can be imported via iCal or CSV upload. More integrations are planned.

Masters is particularly useful for return-to-training — surfacing risky load spikes and highlighting trends that often precede setbacks, within conservative, bracket-appropriate limits.

Rolling 12 months for trend analysis and seasonal comparisons. Data older than 12 months is automatically removed.

No. It complements coaching and structured plans by translating training signals into consistent, research-informed risk monitoring.

Your data is never sold or shared. We apply health-data-level protections, you can export or delete everything at any time, and we comply fully with Strava’s API terms.
